A straight forward design for various applications, bubble-tight if required, following all international standards. Available in all exotic material grades. These types of check valves are specifically designed for fast-reversing systems where backflow is a constant concern. We have a simple, in line design, which responds quickly to changes in velocity. Key elements are; non-slam […]
Gate valves, also known as knife valves or slide valves, are linear motion valves in which a flat closure element slides into the flow stream to provide shut-off. Over 60 years of experience is in this design. Cement, completion fluid, drilling mud, nitrogen and cold start air are just a few applications where we have […]
Instrumentation valves require a different (engineering) approach than the valves in the oil and gas industry. But for Merwede, this product line is common practice. From needle valves, straight type, to customized manifold with optimal CV values. To meet most flow, pressure and level measurement application requirements, Merwede manifolds are designed for static pressure and […]
The broad spectrum of valves in this industry positively encouraged us to get the most out of our engineering staff. LNG/LPG transport with tight FE regulations in place and also on/off loading of crude oil at the middle of the oceans requires skills and ‘no room for failure’.
The rotary valves have been developed for low pressure drop applications. Depending on the application, we can supply a double or a triple offset design. To ensure low seating torques, we have designed with our professional partners a state of the art spring-energized seal for our soft seated butterfly valves. TC coating is applied to […]
